Excellent optical performance that satisfies experienced users
This lens incorporates 4 FLD (F Low Dispersion) glass elements for optimum image quality. The most appropriate optical glass elements are selected to optimize all focal lengths of the lens. From wide angle to telephoto and macro ranges, it offers superior image quality throughout the entire zoom range. It compensates for the distortion very well, especially at wide-end, and carries extraordinary expressive capability from the centre to the corners.
A Newly Developed OS system
The minimum focusing distance of the lens is 39cm, its maximum magnification ratio is 1:3 and the working distance is 14cm, which is similar to macro lenses. In addition to this, a close-up lens, AML 72-01 (optional accessory), is developed exclusively for this product. It makes the rendering very constant across the zoom range, and it enables higher performance in macro photography at 1:2. Even when this close-up lens is attached, the image taken at maximum magnification ratio, at 300mm, infinity, shows very little difference in MTF.
* Focus is at infinity, and the recommended shooting range is 80-300mm.
Zoom-macro for enhanced macro photography
Just by rotating the zoom ring, it enables photographers to take close-up pictures of subjects such as jewelry and flowers. Maximum magnification ratio at respective focal lengths is indicated on the lens barrel, thus it is easy to see what the object size will be at the sensor. Furthermore, in order to secure a clear field of view, the design of this lens is very thorough, even down to the precise position of the engraved letters on the lens.
Brass made bayonet mount
This lens incorporates a brass bayonet mount which has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term user.
Newly Developed Hyper Sonic Motor
For comfortable and smooth use with the high zoom ratio, 16.6 times, it incorporates a bigger HSM (Hyper Sonic Motor) which is newly developed for this lens. It is powerful enough to ensure high speed and quiet AF.
Designed to minimize flare and ghosting
Flare and ghosting were thoroughly measured and monitored from the lens development stage to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.
Corresponding Digital SLR Cameras
DC lenses have an image circle that covers APS-C size image sensors. Not for use on digital cameras having image sensors larger than APS-C size or on 35mm or APS film cameras, as vignetting will occur. The angle of view varies depending on which camera the lens is mounted on. To find the 35mm camera-equivalent focal length, multiply the DC lens focal length by the crop factor (digital multiplier) of 1.5, 1.6, or 1.7, depending on the brand of DSLR camera on which the lens will be used. To find which DC lens is equivalent to a full-frame lens, divide the focal length of the full frame lens by the same crop factor.
Exclusive Close Up Filter
The Close-Up Lens AML72-01, sold separately has been designed exclusively for this lens. It offers a maximum magnification ratio 1:2 and changeable angles of view enables zoom-macro photography. Just by rotating the zoom ring, it enables photographers to take a close up pictures of subjects such as jewelry and flowers.
